Following are a number of back-translations as well as a sample translation for translators of 1 Samuel 25:21:

• Kupsabiny: “Before they met, David was thinking that, ‘Did we really help Nabal for nothing? We were guarding his wealth in the wilderness! He/They completely did not lose anything when we were together with them. So he has done me bad things to exchange the good I did to him.’” (Source: Kupsabiny Back Translation)
• Newari: “David was thinking like this, [lit. had been keeping in his mind like this] "It was in vain that we protected the property of these people in the desert so that nothing at all got lost. In return for the good that I did he did me evil.” (Source: Newari Back Translation)
• Hiligaynon: “(It) has- not -been-a-long-time David said, ‘(It) has-been-of-no-value — my watching-over the properties of Nabal in the desolate-place so-that nothing would-go-missing/be-lost. His pay-back to me (is) evil for my goodness to him.” (Source: Hiligaynon Back Translation)
• English: “David had been saying to his men, ‘It was useless for us to protect that man and all his possessions here in this desert. We did not steal anything that belonged to him, but he has done evil to me in return for our good things we did for him.” (Source: Translation for Translators)
